Description
La présente invention est du domaine des véhicules automobiles, en particulier des véhicules automobiles comprenant un module de face avant. La présente invention concerne en particulier un déflecteur d'air pour un module de face avant. L'invention concerne aussi un véhicule automobile, comprenant au moins un tel déflecteur d'air. L'invention concerne également un support pour module de face avant propre à recevoir des équipements et à être fixé sur la structure du véhicule et comprenant notamment un dispositif d'échange thermique. L'invention concerne encore un module de face avant pour véhicule automobile, du type comprenant un tel support.The present invention relates to the field of motor vehicles, in particular motor vehicles comprising a front face module. The present invention relates in particular to an air deflector for a front panel module. The invention also relates to a motor vehicle, comprising at least one such air deflector. The invention also relates to a support for a front panel module suitable for receiving equipment and for being fixed to the structure of the vehicle and comprising in particular a heat exchange device. The invention also relates to a front panel module for a motor vehicle, of the type comprising such a support.
Un module de face avant est un élément structurel du véhicule destiné à supporter divers équipements du véhicule, tels que projecteurs, clignotants, avertisseur sonore, dispositif d'échange de thermique, groupe moto-ventilateur, etc. Le module de face avant comporte, à cet effet, un support destiné à recevoir les équipements mentionnés ci-dessus. À l'issue de la production d'un module de face avant, celui-ci peut être assemblé sur le véhicule automobile, notamment avec des éléments du châssis du véhicule automobile, tels que les longerons.A front panel module is a structural element of the vehicle intended to support various vehicle equipment items, such as headlamps, indicators, horn, heat exchange device, motor-fan unit, etc. The front face module comprises, for this purpose, a support intended to receive the equipment mentioned above. At the end of the production of a front face module, it can be assembled on the motor vehicle, in particular with elements of the chassis of the motor vehicle, such as the side members.
Le module de face avant comporte généralement un bouclier pourvu d'au moins une entrée d'air afin de permettre l'écoulement d'un flux d'air vers un dispositif d'échange thermique disposé au sein du module de face avant. Selon une solution connue, le bouclier présente deux entrées d'air, dites voie haute et voie basse, séparées par une poutre parechoc. Derrière cette poutre parechoc est généralement placé le dispositif d'échange thermique du véhicule automobile.The front face module generally comprises a shield provided with at least one air inlet in order to allow the flow of an air flow towards a heat exchange device arranged within the front face module. According to a known solution, the shield has two air inlets, called high track and low track, separated by a bumper beam. Behind this bumper beam is generally placed the heat exchange device of the motor vehicle.
Le dispositif d'échange thermique est par exemple utilisé pour le refroidissement du moteur ou encore pour la climatisation de l'habitacle.The heat exchange device is for example used for cooling the engine or for air conditioning the passenger compartment.
Le dispositif d'échange thermique comporte généralement un échangeur thermique, tel qu'un radiateur de refroidissement du moteur. Un tel radiateur placé en face avant du véhicule peut être atteint par un flux d'air externe, provenant de l'extérieur du véhicule et passant généralement au préalable à travers la calandre du véhicule. Un fluide de refroidissement circule à l'intérieur du radiateur de façon à échanger de la chaleur avec ce flux d'air externe.The heat exchange device generally comprises a heat exchanger, such as an engine cooling radiator. Such a radiator placed on the front face of the vehicle can be reached by an external air flow, coming from outside the vehicle and generally passing beforehand through the grille of the vehicle. Cooling fluid circulates inside the radiator so as to exchanging heat with this external air flow.
En variante, le dispositif d'échange thermique peut comporter encore au moins un autre échangeur thermique comme le condenseur d'une boucle de climatisation du véhicule.As a variant, the heat exchange device can include at least one other heat exchanger such as the condenser of an air conditioning loop of the vehicle.
Il est également connu de disposer un panneau de volets, dans le trajet d'air, généralement devant le dispositif d'échange thermique. La ou les entrées d'air comportent donc des volets avantageusement mobiles permettant d'ouvrir ou d'obstruer ces entrées d'air. Les volets sont généralement montés pivotants sur le panneau autour d'axes parallèles de manière à prendre une multiplicité de positions angulaires différentes entre une position d'obturation bloquant le passage de l'air jusqu'à une position d'ouverture où un flux d'air maximum peut circuler. Un dispositif de contrôle permet, en règle générale, de piloter le fonctionnement des volets mobiles pour ajuster le débit d'air traversant les entrées d'airs et arrivant au dispositif d'échange thermique en fonction des besoins, et permet d'optimiser l'aérodynamisme du véhicule automobile lorsque celui-ci est en fonctionnement. Ainsi, il est possible notamment de fermer les volets mobiles pour accélérer la montée en température d'au moins un échangeur thermique du dispositif d'échange thermique, par exemple en phase de chauffage pour qu'elle soit la plus rapide possible en diminuant la consommation du véhicule automobile, ou au contraire les volets peuvent être ouverts de manière à augmenter l'efficacité du refroidissement.It is also known to have a shutter panel in the air path, generally in front of the heat exchange device. The air inlet (s) therefore comprise advantageously movable flaps making it possible to open or obstruct these air inlets. The shutters are generally mounted to pivot on the panel around parallel axes so as to take a multiplicity of different angular positions between a closed position blocking the passage of air to an open position where a flow of maximum air can circulate. A control device makes it possible, as a general rule, to control the operation of the movable shutters to adjust the flow of air passing through the air inlets and arriving at the heat exchange device as required, and makes it possible to optimize the aerodynamics of the motor vehicle when it is in operation. Thus, it is possible in particular to close the movable shutters to accelerate the rise in temperature of at least one heat exchanger of the heat exchange device, for example in the heating phase so that it is as fast as possible while reducing consumption. of the motor vehicle, or on the contrary the shutters can be opened so as to increase the cooling efficiency.
Cependant, les dimensions prédéterminées des entrées d'air représentent une contrainte pour le débit du flux d'air entrant depuis l'extérieur du véhicule automobile et destiné à refroidir, notamment, les échangeurs thermiques disposés au sein du module de face avant, par aspiration d'air. En particulier, lorsque le véhicule fonctionne à l'aide d'une pile à combustible, il est nécessaire de refroidir très rapidement la pile à combustible lorsque le véhicule automobile est en fonctionnement. Les dimensions actuelles des entrées d'air ne permettent pas d'obtenir un débit suffisant du flux d'air entrant pour garantir un refroidissement optimal des échangeurs thermiques, par exemple, dans des conditions spécifiques de fonctionnement du véhicule automobile.However, the predetermined dimensions of the air inlets represent a constraint for the flow rate of the air flow entering from outside the motor vehicle and intended to cool, in particular, the heat exchangers arranged within the front panel module, by suction. air. In particular, when the vehicle operates using a fuel cell, it is necessary to cool the fuel cell very quickly when the motor vehicle is in operation. The current dimensions of the air inlets do not make it possible to obtain a sufficient flow rate of the incoming air flow to guarantee optimum cooling of the heat exchangers, for example, under specific operating conditions of the motor vehicle.

Ceci est particulièrement intéressant pour un véhicule fonctionnant à l'aide d'une pile à combustible pour lequel les besoins en refroidissement sont importants.Thus, if necessary, in particular when cooling is necessary, the deflector wall is deployed, and it is thus possible to improve the cooling of the front face heat exchangers such as a condenser and / or a radiator. This is particularly advantageous for a vehicle operating with the aid of a fuel cell for which the cooling requirements are important.
Lorsque la paroi déflectrice est escamotée, elle ne forme pas un frein aérodynamique.When the deflector wall is retracted, it does not form an aerodynamic brake.

Le module de face avant 3 comporte un support 5 destiné à supporter divers équipements du véhicule automobile 1, plus précisément divers équipements du module de face avant 3. Le véhicule automobile 1 comprend également un bouclier 7 adapté pour être assemblé sur le support de module de face avant 3 du véhicule automobile 1.The
Le module de face avant 3 comporte en outre au moins une entrée d'air 9. La ou les entrées d'air 9 sont ménagées à l'avant du véhicule automobile sur le bouclier 7, de manière à permettre l'introduction d'un flux d'air F derrière la peau du bouclier 7. La ou les entrées d'air 9 peuvent être agencées de manière sensiblement centrale selon l'axe Y dans le sens de la largeur du véhicule automobile 1.The
Dans l'exemple illustré sur les figures, le bouclier 7 comporte deux entrées d'air 9, respectivement dites voie haute et voie basse. Les deux entrées d'air 9 peuvent être séparées par une structure de pare-chocs. Les entrées d'air 9 sont ici agencées l'une en dessous de l'autre selon l'axe vertical Z du véhicule automobile 1.In the example illustrated in the figures, the
Le module de face avant 3 peut comporter en outre avantageusement un dispositif d'obturation de l'entrée d'air ou des entrées d'air 9, tel qu'un ou plusieurs panneaux de volets 11, respectivement agencés dans une entrée d'air 9 respective. Au sein du ou de chaque panneau de volets 11, les volets peuvent être superposés et disposés parallèlement les uns avec les autres. Avantageusement, il s'agit de volets mobiles, par exemple capables de pivoter, entre une position d'obturation d'une ou des entrées d'air 9, empêchant ainsi l'air de passer, et plusieurs positions intermédiaires jusqu'à une position d'ouverture optimale, permettant à l'air de passer avec le plus grand débit possible.The
Le dispositif d'obturation de l'entrée d'air ou des entrées d'air 9 peut être porté par le support 5 de module de face avant.The device for closing the air inlet or the
Le module de face avant 3 comporte en outre un dispositif d'échange thermique 13 dont l'emplacement est schématisé par un cadre en pointillés sur la
Ce dispositif d'échange thermique 13 est porté par le support 5 de module de face avant.This
Le dispositif d'échange thermique 13 comporte au moins un échangeur thermique 131, 133 tel qu'un condenseur d'une boucle de climatisation 131 et/ou un radiateur de refroidissement 133 du moteur du véhicule.The
Le dispositif d'échange thermique 13 est destiné à être monté, dans le véhicule automobile 1, de manière à être traversé par le flux d'air F provenant de l'entrée ou des entrées d'air 9 représentées sur la
Avantageusement, en référence aux
Le module de face avant 3, et plus précisément le support 5 de module de face avant, comporte en outre au moins un déflecteur d'air 15, également désigné sous le terme de « spoiler » en anglais. Le déflecteur d'air 15 peut former au moins une partie du support 5 de module de face avant ou du bouclier 7, ou encore peut être un élément distinct du bouclier 7 et du support 5 de module de face avant.The
Selon les exemples décrits, le module de face avant 3 comporte deux déflecteurs d'air 15.According to the examples described, the
En outre, le ou chaque déflecteur d'air 15 comporte une paroi déflectrice 150. Le ou chaque déflecteur d'air 15 est destiné à être agencé de façon mobile dans un logement 16 du module de face avant 3. Plus précisément, c'est la paroi déflectrice 150 qui est destinée à être montée mobile. La paroi déflectrice 150 est configurée pour être montée mobile dans le logement 16 entre une position déployée illustrée sur les
Selon le mode de réalisation, dans sa position déployée (
En outre, dans ce mode de réalisation illustré sur les
Dans ce mode de réalisation, le ou chaque déflecteur d'air 15, et donc le logement 16 associé, est agencé à proximité et en amont d'un passage de roue 18, c'est-à-dire une cavité aménagée dans la carrosserie du véhicule 1, et entourant une roue 17. Les déflecteurs d'air 15 peuvent aussi être agencés au niveau des passages de roue 18.In this embodiment, the or each
La paroi déflectrice 150 permet dans la position déployée, de dévier le flux d'air F se dirigeant vers la roue 17 (
De plus, la paroi déflectrice 150 présente une ouverture 151.In addition, the
Cette ouverture 151 est telle que dans la position déployée de la paroi déflectrice 150, comme cela est visible sur les
Selon l'exemple illustré sur les
On peut prévoir tout moyen d'actionnement approprié pour déplacer la paroi déflectrice 150.Any appropriate actuating means can be provided to move the
Afin de passer de la position escamotée à la position déployée et inversement, la paroi déflectrice 150 est par exemple montée mobile en pivotement autour d'un axe de pivotement 19. L'axe de pivotement 19 peut être distinct de la paroi déflectrice 150 ou en variante être réalisé d'une seule pièce avec la paroi déflectrice 150. L'axe de pivotement 19 appartient au déflecteur d'air 15.In order to switch from the retracted position to the deployed position and vice versa, the
Selon le mode de réalisation des
La paroi déflectrice 150 est ici articulée à son extrémité arrière, en référence au sens de marche du véhicule automobile 1 lorsque le déflecteur d'air 15 est monté sur le véhicule automobile 1.The
Selon l'exemple particulier illustré, la paroi déflectrice 150 présente une forme générale sensiblement d'écope, c'est-à-dire de pelle creuse présentant des bords surélevés. Cette forme d'écope est mieux visible sur la
Dans ce mode de réalisation, les parties latérales 153 sont agencées respectivement sur les côtés gauche et droit de la paroi déflectrice 150 et la partie de fermeture 155 forme une partie inférieure de la paroi déflectrice 150 reliant les bords inférieurs des parties latérales 153. Les bords inférieurs des parties latérales 153 correspondent aux bords extérieurs, c'est-à-dire donnant sur l'extérieur du véhicule 1 à l'état monté sur le véhicule 1.In this embodiment, the
De plus, les parties latérales 153 et la partie de fermeture 155 sont reliées à une extrémité à l'axe de pivotement 19.In addition, the
Plus précisément selon l'exemple illustré sur les
Par ailleurs, le support 5 de module de face avant comporte un conduit d'air 21, mieux visible sur les
Le conduit d'air 21 est raccordé au moins à une extrémité du dispositif d'échange thermique 13, tel qu'une extrémité latérale, c'est-à-dire dans le sens de la longueur du dispositif d'échange thermique 13 à l'état monté sur le module de face avant 3. Ainsi, lorsque le déflecteur d'air 15 est déployé, le flux d'air F se dirigeant vers le passage de roue 18 et donc la roue 17, est dévié vers une partie latérale du dispositif d'échange thermique 13, ce qui permet d'améliorer le refroidissement du ou des échangeurs thermique 131, 133.The
Avantageusement, le support 5 de module de face avant comprend encore au moins une trappe d'évacuation d'air 23 visible sur les
Cette trappe d'évacuation d'air 23 comporte au moins une paroi d'obturation 230 agencée mobile de façon à ouvrir ou fermer la trappe d'évacuation d'air 23. Selon l'exemple illustré, la paroi d'obturation 230 est montée mobile en pivotement sur la trappe d'évacuation d'air 23 autour d'un axe de pivotement 25.This
L'ouverture de la trappe d'évacuation d'air 23 permet d'évacuer le flux d'air F ayant traversé le dispositif d'échange thermique 13. En effet, le déploiement de la paroi déflectrice 150 augmente le volume d'air traversant le dispositif d'échange thermique 13, et cette trappe d'évacuation d'air 23 permet de gérer l'évacuation du flux d'air F, en aval du dispositif d'échange thermique 13.The opening of the
La paroi d'obturation 230 est configurée pour ouvrir la trappe d'évacuation d'air 23 lorsque le déflecteur d'air 15 est en position déployée (
On peut prévoir tout moyen d'actionnement approprié pour déplacer la paroi d'obturation 230. À titre d'exemple illustratif et non limitatif, une tringlerie avec renvoi d'angle peut être envisagée de façon à permettre l'ouverture de la trappe d'évacuation d'air 23 en même temps que le déploiement de la paroi déflectrice 150, et inversement, par l'action du moyen d'actionnement de la paroi déflectrice 150.Any appropriate actuating means can be provided to move the
Afin de permettre l'évacuation d'air, la paroi d'obturation 230 présente donc une ouverture par laquelle le flux d'air F en sortie du dispositif d'échange thermique 13 est évacué comme cela est schématisé par les flèches sur la
La paroi d'obturation 230 peut présenter une forme sensiblement similaire à celle de la paroi déflectrice 150 et ne sera donc pas décrite plus en détail. Comme illustré sur les
Comme cela est schématisé sur les
Un exemple ne faisant pas partie de l'invention revendiquée est illustré sur les
De façon similaire au mode de réalisation, dans cet exemple deux déflecteurs d'air 15 sont prévus. Chaque déflecteur d'air 15 peut former ou non au moins une partie du support 5 de module de face avant ou du bouclier 7. En particulier, chaque déflecteur d'air 15 est distinct du bouclier 7 et du support 5 de module de face avant.Similar to the embodiment, in this example two
L'exemple diffère du mode de réalisation en ce que les déflecteurs d'air 15 ne sont plus disposés en amont des roues avant 17 du véhicule 1.The example differs from the embodiment in that the
Les déflecteurs d'air 15 sont selon cet exemple à l'état monté sur le véhicule 1, agencés sur une partie latérale du véhicule 1, de sorte que la paroi déflectrice 150 dépasse latéralement du véhicule 1 dans la position déployée.The air deflectors 15 are according to this example in the state mounted on the
Plus précisément dans cet exemple les déflecteurs d'air 15 sont situés sur les côtés latéraux du module de face avant 3 dans la partie supérieure du module de face avant 3.More precisely in this example the
Par ailleurs, pour une continuité esthétique du bouclier 7, et plus généralement du véhicule automobile 1, la paroi déflectrice 150 est conformée de manière à s'inscrire dans la continuité de la carrosserie du véhicule 1, notamment du bouclier 7, lorsque le déflecteur d'air 15 est dans la position escamotée. Autrement dit, la paroi déflectrice 150 est telle que sa partie de fermeture 155 est affleurante à la carrosserie du véhicule 1, notamment au bouclier 7, dans la position escamotée du déflecteur d'air 15 et à l'état monté sur le véhicule 1.Furthermore, for aesthetic continuity of the
De façon similaire au mode de réalisation, la paroi déflectrice 150 présente une forme générale sensiblement d'écope, avec deux parties latérales 153 opposées et une partie de fermeture 155 reliant les deux parties latérales 153. Dans cet exemple, les parties latérales 153 forment respectivement des parties supérieure et inférieure de la paroi déflectrice 150, tandis que la partie de fermeture 155 est agencée sur un côté gauche ou droit du déflecteur d'air 15.Similar to the embodiment, the
Dans cet exemple, la partie de fermeture relie les bords extérieurs des parties latérales, c'est-à-dire les bords orientés vers l'extérieur du véhicule 1 à l'état monté sur le véhicule 1.In this example, the closure part connects the outer edges of the side parts, that is to say the edges facing outwardly of the
Enfin, selon cet exemple, l'axe de pivotement 19 du déflecteur d'air est sensiblement parallèle à l'axe vertical Z s'étendant dans le sens de la hauteur du support 5 de module de face avant à l'état monté sur le véhicule 1. Ainsi, à l'état monté sur le module de face avant 3 ou plus généralement sur le véhicule 1, la paroi déflectrice 150 pivote latéralement vers la gauche ou la droite pour passer de la position escamotée (
